Keystroke logging, often referred to as
keylogging or
keyboard capturing, is the action of recording (or logging) the keys struck on a
keyboard, typically in a covert manner so that the person using the keyboard is unaware that their actions are being monitored.
[1] It also has very legitimate uses in studies of human-computer interaction. There are numerous keylogging methods, ranging from hardware and software-based approaches to
acoustic analysis.
